Sleep is your upgrade.
The visastar MundFix holds the mouth gently closed during sleep. That supports the optimal CPAP pressure, reduces disruptive mouth breathing and can noticeably lower snoring noise.

What changes in your night.
Many CPAP users do not know: if the mouth opens at night, the air escapes. Mouth and throat dry out, and the treatment becomes less comfortable.

“My personal effect: since I started wearing the MundFix at night, I wake up without the neck complaints I used to have. During the day I feel fitter and get more done at work.”
Snore up to 80% more quietly*
CPAP builds up pressure. With the mouth open it escapes and the effect is reduced.
Less dryness in mouth and throat thanks to nasal breathing.
Longer, calmer CPAP use across the night.
The band supports the neck. Less tossing and turning, a calmer neck in the morning.
No pull over the ears, no plastic in the mouth.
Wake up more rested and start the day fitter.
*Own measurement with a snoring app. Not a medical device, not a replacement for your CPAP mask.

The problem
Your night has more trouble spots than just the mouth.
The wrong pillow, a new mattress, an unfamiliar hotel bed, flying upright. You move all night long, and no two bodies are built the same. Not every night can be set up perfectly.
Snoring
When the mouth is open, breathing gets loud. The person next to you notices first — and is often already lying awake.
Dry mouth
Anyone who breathes through the mouth wakes up with a dry throat. Usually in the middle of the night, usually every night.
Under the CPAP mask
The mask blows air into the nose. If the mouth is open, it escapes again straight away — as if you were blowing into a balloon with a hole in it.
A tense neck
The head drops to the side, the neck twists, and you only notice it in the morning. In Switzerland roughly one adult in seven reports neck pain each year.†
A new bed, a new pillow, a tablet against the restlessness. Or quite simply: the visastar MundFix closes the mouth and supports the neck.
† University of Zurich, EBPI health blog, 29.08.2025.
The solution
Simply mechanical.
The visastar MundFix keeps the mouth closed during sleep. That way the air takes the route it was meant to take: through the nose.

- Gentle support
- The MundFix sits around the neck and supports the jaw from below. No band over the head, no pull on the jaw joint — that is the difference from a chin strap.
- Soft material
- Memory foam with polyester and silicone, perforated and latex-free. 50 g light, an infinitely adjustable hook-and-loop fastening, no buckles, no metal parts. Hand washable.
- Simple, every night
- Put it on, adjust the fastening, sleep. One size for a neck circumference of 32 to 46 cm. No power, no splint, no getting used to a device.
Not a medical device within the meaning of the Swiss MedDO. The difference between a chin strap and a neck band
In comparison
Seven methods. One clear difference.
This is how the MundFix compares with everything else you have tried against snoring, sleep apnoea and a tense neck.
CPAP
- Snoring
- Helps
- Sleep apnoea
- Helps
- Neck
- Does not help
The established gold standard for sleep apnoea. Keeps the airways open with positive pressure.
Chin strap
- Snoring
- Does not help
- Sleep apnoea
- Does not help
- Neck
- Does not help
Pulls from above over the crown of the head, often pressing uncomfortably on jaw and ears.
Mandibular splint
- Snoring
- Partly
- Sleep apnoea
- Partly
- Neck
- Does not help
Sits inside the mouth, the mouth can still open, and it puts strain on the teeth.
Pillow
- Snoring
- Partly
- Sleep apnoea
- Partly
- Neck
- Partly
Helps only in certain sleeping positions. We move during the night.
Surgery
Success rate around 50%
- Snoring
- Partly
- Sleep apnoea
- Partly
- Neck
- Does not help
A surgical procedure with risks, and success is not guaranteed.
Hypoglossal nerve stimulator
surgically implanted
- Snoring
- Helps
- Sleep apnoea
- Helps
- Neck
- Does not help
Works reliably, but is a major surgical procedure.
visastar MundFix
- Snoring
- Helps
- Sleep apnoea
- Only with CPAP
- Neck
- Helps
Helps with sleep apnoea only in combination with CPAP: the pressure no longer escapes through the open mouth, so the mask can do its job fully.
Not a medical device within the meaning of the Swiss MedDO. Registered with Swissmedic and classified as a lifestyle product until the classification decision.
How it works
A closed mouth changes three things.
80%
up to · quieter snoring
Recorded in our own comparative measurement with a snoring app over several nights. Individual results may differ.
- It goes quiet
- You breathe through the nose instead of the mouth. The person next to you notices first.
- The throat stays moist
- With a CPAP mask the air stays where it belongs. No bone-dry throat at four in the morning.
- The neck lies at rest
- The soft band supports the neck in a calm position. Less tossing and turning, no tense neck in the morning.
Recorded
Two screenshots say more than two pages of text.
You do not have to take our word for it. This is what a sleep app recorded during one night with the MundFix: sleep quality 92 out of 100 and breathing that stayed calm all night. That is exactly the difference between “I slept” and “I woke up rested”.

92 out of 100. “Excellent.”
A night slept through from 00:38 to 07:00 — with the MundFix around the neck. The app rates what it measures, not what we claim.

Calm. All night long.
That is exactly the point: mouth closed, the nose takes over, breathing stays even — instead of the cycle of snoring, startling awake and a dry throat.
A night like that costs CHF 39 — and if your nights are no better after 14 nights, you get the purchase price back. No return shipment, no discussion.
Our own recording with a sleep app, one night with the MundFix. It documents everyday use and does not replace a clinical assessment. The MundFix is not a medical device and not a replacement for your CPAP mask.
On the move
With you everywhere. 50 grams.
Your sleep does not stop at the front door. The MundFix weighs so little that you take it anywhere — and wake up without a tense neck in the morning, even after sleeping upright.

Put it on, close the fastening, sleep. The head does not drop to the side.

Two hours of travel are two hours of sleep. The mouth stays closed, even seated.
- 50 grams
- About as much as a handful of coins. You will not notice it in your luggage.
- Lies flat in your bag
- Rolled up it is the size of a fist, in hand luggage or in a laptop bag.
- No power, no accessories
- No battery, no cable, no power supply. Nothing that raises questions at the airport.
Sleep calmly, from the very first night.

Stimmen
Worte aus der Praxis.
Von Anwender:innen, Partner:innen und aus der pneumologischen Sprechstunde, die klare Empfehlung eines Schweizer Facharztes, der den MundFix mitgeprägt hat.
„Mund zu während der CPAP-Therapie. Das ist die Regel, auf die es ankommt."
Der Leitsatz aus seiner CPAP-Sprechstunde: geschlossener Mund während der Nacht. Genau dafür ist der visastar MundFix gemacht, vom Gründer (selbst CPAP-Träger) erprobt und von Dr. Al-Nasser empfohlen.
Drei Jahre habe ich mit der Maske gekämpft. Der MundFix war die Woche, in der ich endlich wieder durchgeschlafen habe.
Ich hörte ihn jede Nacht. Jetzt nicht mehr. Wir schlafen wieder im gleichen Zimmer, nach zwei Jahren Exil im Gästezimmer.
„Inzwischen habe ich den MundFix drei Nächte ausprobiert und bin rundum zufrieden."

Garantie III
Drei Jahre Praxis.

Vom Gründer
„Es gab Nächte, da hatte ich Angst, nicht mehr aufzuwachen."
Ich bin selbst CPAP-Patient. Mein Mund fiel nachts auf, der Druck entwich, die Therapie lief ins Leere. Morgens war ich wie zerschlagen, und ohne funktionierende Therapie waren meine Apnoe-Werte gefährlich.
Dann sagte mein Pneumologe den einen Satz, der alles veränderte: nachts muss der Mund geschlossen bleiben. Der MundFix tut genau das. Drei Jahre habe ich ihn jede Nacht selbst getragen und heute kann ich damit anderen Menschen helfen. Seither schlafe ich durch. Drei Jahre, jede Nacht, und ich habe alles dokumentiert.
Wirkt er bei Ihnen nicht, bekommen Sie jeden Franken zurück. Das ist kein Marketing-Satz. Das ist mein Wort.
Arthur, Gründer von visastar
